Side Discharge The mower has a hinged discharge deflector that disperses clippings to the side and down toward the turf. Loading a unit on a trailer or truck increases the possibility of backward tip-over. Backward tip-over could cause serious injury or death. • Use extreme caution when operating a unit on a ramp. Without the discharge deflector, mulch kit, or entire grass collection system mounted in place, you and others are exposed to blade contact and thrown debris.
Avoid Cutting Too Low Avoid sudden acceleration when driving up a ramp and sudden deceleration when backing down a ramp. Both maneuvers can cause the unit to tip backward. If the cutting width of the mower is wider than the mower you previously used, raise the cutting height to ensure that uneven turf is not cut too short.

A fire or explosion from gasoline can burn you and others and can damage property. 3.
Electrical System Maintenance Warning CALIFORNIA Proposition 65 Warning Battery posts, terminals, and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling. Charging the Battery Figure 31 1. 2. 3. 4. 5. Fuel tank Fuel shut off valve—off Fuel shut off valve Fuel shut off valve—on Fuel line from tank 6. 7. 8. 9.
3. Check the voltage of the battery with a digital voltmeter. Locate the voltage reading of the battery in the table below and charge the battery for the recommended time interval to bring the charge up to a full charge of 12.6 volts or greater. Important: Make sure the negative battery cables are disconnected and the battery charger used for charging the battery has an output of 16 volts and 7 amps or less to avoid damaging the battery (see chart below for recommended charger settings). Figure 32 1. 2. 3.
2. Install the positive (red) battery cable to the positive (+) battery terminal using the fasteners removed previously Drive System Maintenance 3. Install the negative battery cable to the negative (-) battery terminal using the fasteners removed previously. Checking the Tire Pressure 4. Slide the red terminal boot onto the positive (red) battery post. Service Interval: Every 25 hours/Monthly (whichever comes first) 5. Secure the battery with the hold-down (Figure 32).
Hydraulic System Maintenance 5. Remove the vent plug on each transmission and fill through expansion reservoir, when oil comes out of vent reinstall plug. Torque plugs to 180 in-lb (244 N-m). Continue to add oil until it reaches the FULL COLD line on the expansion reservoir. Checking the Hydraulic Oil Level Service Interval: Before each use or daily Check expansion tank and if necessary add MOBIL 1 15W-50 synthetic motor oil to the FULL COLD line Figure 37 1. Oil filter 2. Vent plug 6.
Mower Maintenance Servicing the Cutting Blades Service Interval: Before each use or daily Maintain sharp blades throughout the cutting season because sharp blades cut cleanly without tearing or shredding the grass blades. Tearing and shredding turns grass brown at the edges, which slows growth and increases the chance of disease. Figure 38 1. Cutting edge 2. Curved area Check the cutter blades daily for sharpness, and for any wear or damage. File down any nicks and sharpen the blades as necessary.
Checking for Loose Blades or Damaged Spring Disc Washers 1. Place a wrench on the blade bolt and torque to 45-55 ft lb (61-75 N-m). 2. With the wrench still on the blade bolt, hold the blade spindle stationary and using a rag or thickly padded glove, try to rotate the blade. If the blade rotates relative to the spindle guard without further tightening the blade bolt, the spring disc washer has been flattened or damaged and the bolt and washer assembly must be replaced (Figure 40).
11. Recheck that blocks fit just snugly under the deck skirt. Make sure all attachment bolts are tight 2. Move the motion control levers outward to the neutral position, engage parking brake, stop the engine, remove the key, and wait for all moving parts to stop before leaving the operating position. 12. Continue leveling the deck by checking the front-to-rear blade slope; refer to the Adjusting the Front-to-Rear Blade Slope section. 3. Check the air pressure of all four tires.
(5.89 cm) blocks under each side of the front edge of the deck, but not under the anti-scalp roller brackets. 7. Loosen the leveling adjust locking nuts (item 4) on all four corners so that the deck is sitting securely on all four blocks. Make sure that the deck hangers are all the way down (at the top of the slot) and the deck lift foot lever is pushed back against the stop, then tighten the four leveling adjust locking nuts (Figure 45). Figure 46 1. Blades front to rear 2. Outside cutting edges 3.
5. Remove the nut, bolt, and pivot bushing from the deck strut (Figure 47). Carefully lower the front of the mower deck to the ground (Figure 48).

Replacing the Discharge Deflector shorter spring end is coming from under the rod before the bend and going over the rod as it returns from the bend. 4. Lift the long end of the spring and place it into the notch on the deflector assembly bracket (Figure 51). An uncovered discharge opening could allow the lawn mower to throw objects in the operator’s or bystander’s direction and result in serious injury. Also, contact with the blade could occur.
Cleaning A broken or missing washout fitting could expose you and others to thrown objects or blade contact. Contact with blade or thrown debris can cause injury or death. Washing the Underside of the Mower Service Interval: Before each use or daily • Replace broken or missing washout fitting immediately, before using mower again. After each use, wash the underside of the mower to prevent grass buildup for improved mulch action and clipping dispersal. 1.
Storage F. Dispose of fuel properly. Recycle as per local codes. Cleaning and Storage Important: Do not store stabilizer/conditioned gasoline over 30 days. 1. Disengage the blade control switch, move the motion controls outward to the neutral position, engage parking brake, stop the engine, and remove the key. 2. Remove grass clippings, dirt, and grime from the external parts of the entire machine, especially the engine.
Troubleshooting Important: It is essential that all operator safety mechanisms be connected and in proper operating condition prior to mower use. When a problem occurs, do not overlook the simple causes. For example: starting problems could be caused by an empty fuel tank. The following table lists some of the common causes of trouble. Do Not attempt to service or replace major items or any items that call for special timing of adjustments procedures (such as valves, governor, etc.).
